Email uses a variety of technologies to ensure the transmission is secure, including Simple Mail Transfer Protocol (SMTP), Multipurpose Internet Mail Extension (MIME), and the Hypertext Transfer Protocol (HTTP). Email also uses a system of computers, networks, routers, and applications to send the message from sender to recipient. Finally, email clients, such as Outlook and Gmail, are commonly used to organize and manage emails.
